Please ensure you complete and attach the relevant schedules to your application.

Generation management applications with energy smoothing will undergo a Network Impact Assessment. Applications that also require feed-in management or zero export will need a System Impact Study and a fee applies. Horizon Power cannot confirm these costs until after the study is completed.

Please be mindful that even when you feel you have complied with all the technical requirements, there is no guarantee that your application will be approved. For example, an application may not be accepted due to local network constraints, something you have no control over.

You cannot proceed with any installation until the customer has received approval from Horizon Power in writing.

Included in the technical requirements are specifications for generation managed renewable energy installations. In these installations, the electricity output is controlled or managed to help maintain the reliability of power supply to all our customers. Visit the Generation Management page.

The quick reference table provides an overview of the generation management requirements for each class of installation. Please refer to the Technical Requirements for Renewable Energy Systems Connected to the Low Voltage (LV) Network via Inverters full details. The customer's electrical installation needs to be designed according to specific system and circuit diagrams to ensure a compliant connection, as per the table.

Some specific applications may also require zero export or feed in management as part of the Horizon Power technical assessment process.

Complete the checklist and enter any relevant comments. The checklist must be attached to all applications.

Schedule 2

System Diagram

This is a conceptual diagram that illustrates the functional relationships between key subsystems using solid lines. The Customer’s System Diagram shall be in accordance with section 5.1 of the Technical Requirements.

This includes one or more diagrams detailing the electrical connections from the point of connection through to the renewable energy source. The Customer’s Circuit Diagram shall be in accordance with section 5.2 and the other requirements of the Technical Requirements.

Cable data must be attached to all applications, except for Class 3 system size which will be requested it at a later stage

Schedule 5

National Professional Engineers Register (NPER) sign-off letter

For Class 1 and 2 installations that require Generation Management, a NPER accredited engineer shall validate that the design is in accordance with the Technical Requirements. An installer may reuse a NPER declaration for multiple installations providing the installations do not differ with the NPER validated reference design in certain elements.

For every Class 3 installation, a NPER accredited engineer shall validate that the design is in accordance with the Technical Requirements and provide supporting documentation. NPER accreditation for Class 3 installations cannot be reused.

Frequently asked questions

Please note: if your intent is to supply the renewable energy generated back to Horizon Power as a power producer, then your 'tariff' is IPP (Independent Power Producer). Horizon Power is unable to offer a renewable energy contract to M2 customers with high voltage supply connections.

Eligibility for Class 3 system sizes (50-1000 kW) will also depend on how you intend to use the renewable energy you generate.

Prosumers

If your intent is to connect a renewable energy system to a Horizon Power network to partially generate your own electricity and potentially export excess electricity to the Horizon Power network, then you are a Prosumer.
